Abstract
Adjustable speed AC Motor drives have been used extensively in modern industry and transportation which calls for electrical and mechanical energy conversion with wide output power range applications. Because of its modularity and scalability, the drive system can be extended to many different application areas. More recently, adjustable speed AC motor drive applications are spreading not only in industry applications, but also sky and the marine. In this paper, after summarizing the history of adjustable speed AC motor drives and applications, the main issues of AC drive technologies are reviewed and investigated in the paper. Technical issues of adjustable speed AC motor drives including its standardization are surveyed and analyzed for more advancement. Finally, the paper provides the latest technical trends on adjustable speed AC motor drives technologies, and discusses the development of high speed high power PM motor.
Highlights
Adjustable speed AC motor drives have attracted increasing attention for more than half of the last century as one of the preferred choices of electric energy conversion for the high-power applications[1], for industry application, transport applications and so on
(2) Expanding Japanese economy caused the enlargement of business area, where power electronics and drives could be introduced
In middle/low speed type, flat PMSM technology was introduced as a key component of machine-room-less elevator after moving to inverter drive of IM
Summary
Adjustable speed AC motor drives have attracted increasing attention for more than half of the last century as one of the preferred choices of electric energy conversion for the high-power applications[1], for industry application, transport applications and so on. 1891 – Ward-Leonard speed control was introduced 1948 – Transistor was invented at Bell Labs 1956-1957 – Power diode and thyristor (SCR) was introduced by GE 1961 – Impulse-commutated inverter was introduced 1964 – “Principles of Inverter Circuit” was published (almost all AC drive main circuit topologies using thyristors were introduced) 1964 – First high-speed railway “Shinkansen” using DC drive with diode rectifiers began operation in Japan 1964 – Electric vehicle “Electrovair1” using IM drive of thyristor inverter with Silver-Zinc Battery was introduce by GM 1969 – Dissertation on dynamic speed controlled drive was introduced 1971 – Flux detecting vector control was introduced 1974 – PWM technique for single-phase converter in railway application was introduced 1975 – Giant transistor GTR was commercialized 1978 – Power MOSFET was introduced 1980 – High-power GTOs were commercialized 1981 – 3 level inverter was introduced 1987 – IGBT was commercialized 1996 – First mass-produced and purpose-designed Electric vehicle was introduced (Prototype in1990) 1997 – Hybrid electric vehicle “PRIUS” was commercialized 2009 – Electric vehicle “i-MiEV” was commercialized 2012 – Large-capacity SiC diode was introduced in rail application needs have driven power requirements and manufacture of motor products to meet the demands of each age From the latter of 1970s to 2000s, the existence of industrial vitality requiring better performance of drives compared to former days is the reason why progress in motor drive technologies in Japan has been very active
